CHIN117 is a dual cysteinyl leukotriene receptor 1 (CYSLTR1) antagonist and G‐protein‐coupled bile acid receptor 1 (GPBAR1) agonist. In the liver, GPBAR1 and CYSLTR1 are coexpressed by liver sinusoidal endothelial cells (LSECs), HSCs, circulating monocytes/macrophages, and liver resident macrophages (Kupffer cells).

Synthesis of some new substituted imines from aldehydes and ketones derived from quinolinic acid
In this paper, some substituted imines compounds have been prepared from quinolinic acid as a starting material. Firstly, the quinolinic acid was treated with acetic anhydride and acetic acid to form furo[3,4-b]pyridine-5,7-dione (1); the resulting ...

Quinolinic Acid: Neurotoxin or Oxidative Stress Modulator? [PDF]
Quinolinic acid (2,3-pyridinedicarboxylic acid, QUIN) is a well-known neurotoxin. Consequently, QUIN could produce reactive oxygen species (ROS). ROS are generated in reactions catalyzed by transition metals, especially iron (Fe). QUIN can form coordination complexes with iron.

Vagus Nerve Stimulation in Refractory Epilepsy: Effects on Pro- and Anti-Inflammatory Cytokines in Peripheral Blood [PDF]
Objective: The vagus nerve has important immunological functions that may be relevant for its anticonvulsive action. We postulate that this anticonvulsive action is activated by a shift in the immune system resulting in a reduction of neurotoxic and an ...

M. tuberculosis induces potent activation of IDO-1, but this is not essential for the immunological control of infection. [PDF]
Indoleamine 2,3-dioxygenesae-1 (IDO-1) catalyses the initial, rate-limiting step in tryptophan metabolism, thereby regulating tryptophan availability and the formation of downstream metabolites, including picolinic and quinolinic acid.
